Abstract: A machine adapted for barking and cleaning a log, having jet nozzles, and featuring mounting each jet nozzle on its own log feeler arm for individual displacement of the jet nozzles in accordance with the hills and valleys sensed by the log feeler arms at the periphery of the log, whereby to automatically and individually maintain each nozzle at a predetermined spacing from the bark. This log barking and cleaning machine further comprises an endless conveyor defining a log path, a support structure extending around the log path, log feeler arms pivoted at one end to the support structure, and having a liquid jet nozzle at the other end, a spring wire connected to each arm and biasing the latter toward operative log feeling contact with the periphery of the log, means to adjust the bias of each spring wire, and a liquid manifold and hydraulic supply tubes connected to the nozzles to feed pressurized liquid through the nozzles.

Abstract: An apparatus for cooling plastic sheathed wires after the sheathing operation comprises two concentric tubes where the compartment between the tubes acts as a manifold for numerous nozzles directing jets of compressed air into the inner tube. A water stream flows along the inner wall of the inner tube and the water is atomized when passing the nozzles. The water mist formed is given a turbulent motion by the air jets causing an efficient cooling of the plastic sheath.

Abstract: The efficiency of a multi-stage rinsing operation is improved by routing a substantial portion or all of the overflow rinse liquor from the collecting tank of one stage directly to the spray rinse of the next succeeding stage along with rinse liquor from said succeeding stage. Improved cleanliness of the rinse liquor at each rinse stage is thereby attained while maintaining a self-regulating rinse system.

Abstract: An air wipe device to direct linearly displaced opposing jet streams of compressed air or pressurized solvent, to incrementally remove adhering particulate matter from a linearly drawn article of indefinite length passing through a central channel. The air wipe is characterized by a plurality of transverse extrusion channels defined by oblique swept baffles, each extrusion channel having mediately positioned opposing jet stream orifices and each channel further communicating and merging with longitudinal exhaust channels coaxial with the central article channel, the exhaust channels terminating in exhaust ports adjacent to, but displaced from, a central wire entrance orifice.

Abstract: An apparatus for etching a continuously moving thin metal strip in which the length of the etching compartment is adjustable to adapt the etching duration to the thickness of the strip. The length is adjustable by means of a movable housing which comprises closure means through which the strip enters or leaves the etching compartment.

Abstract: This invention relates to a device for regulating the water level in apparatus for treating an insulated electrical conductor, which device comprises two or more gates actuated by a control signal for filling and emptying the apparatus, a first control circuit having a broad range of adjustment, a second control circuit having a narrow range of adjustment, and an inverter, each circuit in turn comprising a first transmitter for producing a measuring signal, a second transmitter for transmitting a reference signal, and a comparator for producing a control signal and transmitting same to the inverter, the inverter supplying the control signal from the comparator of the first or of the second circuit to the gates.

Abstract: In an electrostatic high speed line printer, a pair of lightly wetted cylindrical rollers are sequentially arranged upstream of the print station to engage the paper surface to be printed. The roller surfaces are wetted with a very thin film of non-staining viscous film such as isopar, and driven at roughly the same speed as the paper causing the paper surface to be very slightly wetted, thereby tending to attract debris particles from the surface of the paper to the roller and also tending to cause other debris particles to be adhered to the paper surface at least until after they have passed through the print head. A dancer roller is positioned on the opposite side of the paper from the wet rollers, between the wetted rollers, to provide approximately 30.degree. of wrap across each wetted roller.

Abstract: An apparatus for the direct cooling of a strand, especially during the continuous casting of steel, incorporating strand guide segments equipped with spray nozzles for the application of a cooling agent to the strand. The spray nozzles are arranged at rotatable holders, each holder is equipped with at least two nozzles. A drive mechanism is provided for the stepwise or incremental rotation of such holders and there are provided infeed means for delivering the cooling agent to the spray nozzles.

Abstract: Apparatus for quench hardening the surface of a previously inductively heated, elongated workpiece as it moves along a feed path, this apparatus comprises a quenching means surrounding the feed path, the quenching means includes an inwardly facing apertured wall facing the feed path, means for forcing a quenching liquid through the apertured wall toward the feed path for quenching the surface of the heated workpiece as it passes along the feed path and means for moving the apertured workpiece in a direction generally transverse to the feed path. In the preferred embodiment, the apertured wall is generally circular and is rotated around the workpiece.

Abstract: A method of, and apparatus for, the cooling of a strand during the continuous casting of metals, especially steel, wherein a cooling fluid possessing a regulatable quantity for impingement at the surface of the strand is sprayed between two guide elements neighboring one another in the direction of strand travel onto the strand surface. According to the invention, the cooling liquid or fluid is selectively sprayed from one spray pattern or two spray patterns which are essentially similarly directed and initially extend behind one another in the direction of travel of the strand and thereafter are united into a spray pattern having a flat spray characteristic, wherein the united spray pattern has a thickness and direction which approximately corresponds to that of one of the adjacently situated spray patterns.

Abstract: A manifold is provided for use in the etching or plating of materials which continuously supplies fresh fluid to the surface of an article to be etched while continuously removing the old fluid that is adjacent the surface of the article that is to be etched. The transfer of fluid is accomplished by a plurality of sources and a plurality of funnel-like sinks.

Abstract: The invention relates to a machine for cooling metal wire. This machine comprises a cooling tube, an injection device for the cooling fluid and a bypass device for the cooling fluid. The injection device comprises an oblique annular slot fed under high pressure and injectors fed under low pressure. The bypass device comprises an open elbow extending the tube and a second elbow of an opposite curvature terminating in a direction normal in relation to that of the wire. The invention is applied to the cooling of a metal wire, with or without hardening.
